Abstract

The embodiment of the invention disclosesa performance degradation analysis based intelligent manufacturing device reliability assessment method. The method comprises the steps that 1, analysis is performed: a target performance degradationindex identifying and representing the usage reliability of an intelligent manufacturing device and target environment and working condition stress factors influencing the reliability are analyzed; 2, information acquisition is performed: target performance degradationindex data and target environment and working condition stress factor data are acquired; 3, assessment is performed: modeling analysis is conducted on the acquired target performance degradationindex data, and modeling introduction is conducted on the acquired target environment and working condition stress factor data, and reliability assessment is established by applying a bayesian method. Compared with the prior art, the performance degradation analysis based intelligent manufacturing device reliability assessment method can achieve real-time and efficient assessment of the usage reliability of the intelligent manufacturing device.
